First Task:The Symbol @

Hello Pepe Navarro!

I'm aware that my first task consist in searching for information about the symbol @.

The English pronuntiation of this symbol is at, that means 'en' in Spanish.

In 1971 Ray Tomlinson looked for a symbol to separate the name of the person from the place where it was. Typewriters developed around 1884, had kept the sign @ even though it was no longer used, and the keyboard of a Model-33 Teletype (a teletype model) contained an at that was the sign used by Tomlinson, who sent the first message with it from his digital computer PDP-10 to another one.

This one was the first electronical address in history as we know them now: tomlinson@bbn-tenexa. Nowadays it is well-known by computer users because it is used to indicate in line “at home” in e-mail addresses and other services that use the user@machine format, like for example Jabber.
